To change the default download path for canvas images, you can use the download attribute in the a tag when creating the download link.
Here's an example:
- Assume you have a canvas element with an id of "myCanvas" and you want to save the image drawn on the canvas to a specific file path.
- Create a click event listener on a button that triggers the download action.
- Inside the event listener function, get the canvas element using document.getElementById('myCanvas').
- Use the toDataURL method to get the data URL of the canvas image.
- Create a link element (a tag) with the download attribute set to the desired file name and path.
- Set the href attribute of the link element to the canvas data URL.
- Append the link element to the document body.
- Simulate a click on the link element to trigger the download.
Here's a code snippet that demonstrates this process:

<!DOCTYPE html>
<html>
<head>
<title>Download Canvas Image</title>
</head>
<body>
<canvas id="myCanvas" width="200" height="200"></canvas>
<br>
<button id="downloadButton">Download Image</button>
<script>
document.getElementById('downloadButton').addEventListener('click', function() {
var canvas = document.getElementById('myCanvas');
var dataURL = canvas.toDataURL();
var link = document.createElement('a');
link.download = 'myCanvasImage.png'; // Set the desired file name and path
link.href = dataURL;
document.body.appendChild(link);
link.click();
});
</script>
</body>
</html>

By setting the download attribute of the link element, you can specify the file name and path where the canvas image will be saved when downloaded.
